The dual narratives shows two very different paths on the road to abolishing slavery, and there are a great many events enumerated in the storytelling. In addition, Purvis's artwork is less sketchy than in Sons of Liberty and includes more grey tones, which give it a more painterly sheen. The sum total of these features is an engaging set of tales that balance historical import with human emotion.
I was not able to find many reviews of A House Divided, but Snow Wildsmith praised it particularly because "one of the strongest points of this book (and of the series) is that Poe doesn’t neglect to tell both sides of a story as much as he can" and because "Purvis’ art is also stronger in this volume." I agree with her on both counts.
